The objective of the Fit for Purpose (FFP) effort in Testbed 13 was to develop and test filters and encodings in a platform that can ease the work of end-users, especially those who are not expert in dealing with geospatial data and satellite imagery. The platform was demonstrated in a scenario that showed how these filters can enable information exchange for humanitarian relief and analysis of mass movement of populations.
This section provides a summary of the interoperability tools and practices used by Testbed 13 participants in this platform. It includes descriptions and testing results of filters and encodings to help simplify access to satellite imagery. This technology was tested in a scenario that showed how OGC-based services, encodings, filters and applications can help coordinate humanitarian relief activities among nations and organizations.
1.1. Demonstration Scenario
Testbed 13 focused on addressing challenges related to coordinating multi-regional / multi-national operations and messaging related to the displacement and mass movement of populations in response to conflict . The current exodus of people across the Middle East to multiple nations was used as a scenario for this discussion.
In OGC Testbed 13, participants assessed the ability of open geospatial web services, encodings and filters to support simulated users in a Mass Migration Scenario over Syria and Jordan. In this scenario, large numbers of people have been displaced from the Daraa region of Syria to the Zaatari refugee camp in Jordan due to conflict. As the conflict ends 'de-escalation zones' are established and plans are made to return displaced people from refugee camps. Understanding the situation on the ground and the infrastructure, as well as transporting these people from refugee camps into a former conflict zone is a major challenge for relief agencies. To accomplish this task users must understand the environment and infrastructure in the region between Zaatari and Daraa.
The following examples provide a brief sample of the scenario involved in testing the platform and approach.
